|I noted while browsing that the following two Casio models have a unusual chronograph feature. They allow you to input the distance of a racecourse lap so that when timing a lap you can, per the description, get the lap speed listed as well as the time. It sounds to me like a neat feature to have available. The models with this feature are the GA-100 G -Shock and the AQ-190 Multi Task Gear Sports Watch.
Both are listed as having a 1/1000 second chronograph with max reading of 100 hours, 5 alarms, 24 hour countdown timer and 48 cities world time. Both are combined digital LCD and analog display watches. The Amazon listed price on the AQ-190 starts in the $44 range and the GA-100 starts in the $90 range.
The G shock is larger, more water resistant and more accurate at a rated 15 seconds/month accuracy versus 30 seconds/month specified for the AQ-190. The other difference is the dial layout for the LCD windows on the two watches. The G-Shock is also listed as having a mineral crystal. Functionally though the two watch manuals I downloaded indicate identical capabilities for the two watches so far as I noted. The G-Shock uses a 5081 module/movement and the AQ-190 uses a 5082 module/movement.
